SMC2835W 2.4GHz 54Mbps Wireless Adapter Utility
When Key Type is set to 128-bit, only one key will be generated. If
Key Type is set to 64-bit, four keys will be generated. Note that
you must use the same passphrase and default key on all the
other clients in your network.
How to set up WEP:
If you are transmitting sensitive data across wireless channels,
you should enable Wired Equivalent Privacy (WEP) encryption.
WEP provides a basic level of security, preventing unauthorized
access to the network and encrypting data transmitted between
wireless clients and the access point. WEP uses static shared
keys (fixed-length hexadecimal or alphanumeric strings) that are
manually distributed to all clients that want to use the network.
WEP is the security protocol initially specified in the IEEE 802.11
standard for wireless communications. For more robust wireless
security, the SMC2835W provides Wi-Fi Protected Access (WPA)
for improved data encryption and user authentication.
Note: Only one key is needed for WEP to function. However, the
IEEE 802.11 standard specifies that there must be four keys
for each device. For security purposes, the key should be
changed on a regular basis. Multiple keys are supported to
allow the user to change keys with minimal disruption of the
network.
